Button Layout

I wired the buttons to the PCBs to mirror the MadCatz SF IV sticks:

★Layout 360:
X Y RB LB
A B RT LT

★Layout PS3/PS2/PS1:
[] /\ R1 L1
X O R2 L2

★Gamecube/Wii:
Y X L
B A R
Start = Start
Select = Z

★Xbox:
X Y white LT
A B black RT
Start = Start
Select = Back
Select + X = Left stick click
Select + A = Right stick click
Select + Stick = Left and right analog sticks

So the 360 PCB and the MC Cthulhu board are connected so that RB/LB on the 360 ‘equal’ R1/L1 on the PS3 and RT/LT ‘equal’ R2/L2.

For the PS3 this is also the same layout as the one of the HORI Real Arcade Pros.

The buttons use quick disconnects so the layout can be changed easily. One could also change the lines at the Cthulhu’s screw terminals.
